MAX AUEBBACH, OF BERLIN, GERMANY.

Application filed January 23, 1914, Serial No. 813,

To all whom it may concern Be it known that 1, MAX AUERBAcI-I, a subjectof the German Emperor, residing at Potsdamerstrasse 20, Berlin, Germany,have invented certain new and useful Improvements in AutomaticShuttle-Changing Mechanism for Looms; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to an automatic shuttle changing mechanism forlooms by means of which the ejection of the shuttle carrying the usedspool and the introduction into the shuttle box for a shuttle carrying anew spool are effected in two phases or operations.

Primarily the invention consists of a shuttle box, having a pivoted rearwall, adapted to swing outwardly against spring tension, and avertically sliding front wall, in combination with a shuttle magazine,and means cooperating between said shuttle box and magazine, to causesaid front wall to be raised and a full shuttle to be forced into saidshuttle box, by the outward swing of said rear wall, in ejecting anempty shuttle, and the forward movement of the shuttle box.

The subject matter of the invention is illustrated diagrammaticallyaccording to one method of carrying the same into effect, in the drawingaccompanying the present specification.

Figure 1 is a side elevation with a portion in section; Fig. 2 is aplan, the outlet inclined guide 2 and the container 3 being omitted;Fig. 3 shows the arrangement of the shuttle changing mechanism withrespect 'to the framework of the machine, partly in elevation and partlyin'section.

In the method of carrying out the invention shown in the drawing 1 is ashuttle box, provided at one end with an inclined outlet guide 2 for thepassage of the shuttle carrying the empty spool. This outlet guide 2projects into a holder or container 3. The shuttle box is provided witha wall or partition 5 at the back, which turns around a vertical pivot4. The wall or partition 5 is provided with a springy projecting surface6 in order to cushion or buffer the shuttle thrown into the shuttle box.The pivoted partition 5 is kept pulled inward by the Specification ofLetters Yatent.

action of a tension spring 7 so that its front edge tends to pressagainst the wall 8 of the shuttle box. In this position of the parts, ashuttle entering the shuttle box is caught by the partition andconducted sidewise and outward so that it passes through the inclinedoutlet guide 2 into the container 3. The retention or fixing of thepivoted par tltion 5 in its position parallel to the front wall in whichthe shuttle passes into the shuttle box, is efiected. by a suitablycontrolled stop 9. After this first operation or phase of the ejection,namely the removal of the shuttle carrying the empty spool, has takenplace the introduction of a new shuttle carrying a full spool iseffected in the following manner :At the rear end of the pivotedpartition 5 of the box is a pivot 10, which is connected by means of alink 11 to a two armed lever 12 turning, about a vertical pivot. One armof this two armed lever 12 presses against the arm 13 of a pivotedbell-cranked lever turning about horizontal bearings 14. 15 is thehorizontal arm of this bell-crank lever and it is adapted to support alink rod 16 having a projecting nose 17 which rests thereon. The linkrod 16 is provided with a hook-like projection 18 which in the normalposition of the pivoted partition 5 of the shuttle box, is at a lowerlevel than the fixed projection 19 on the shuttle box 1 so that it canpass freely. When, however, the link rod 16 is raised by the arm 15 ofthe bell-crank lever in the fixed position of the wall 5 ofthe shuttlebox, upon the forward movement the projection 19 engages the projection18 and the link 16 is carried along. This causes the two-armed leverworking on pivots 20 to be turned so that the upper arms 21 act upon therods of slides 23 controlled by springs 22. The slides 23 being pushedforward pass into a recess in the shuttle magazine 24, pushing out thelowermost full shuttle 25, in the direction of the arrow, it beingunderstood that rods or projecting members 23 extend rearwardly from thetops of the slides 23 to support the upper shuttles inthe magazine,during the forward and return movement of the slides, as the lowermostshuttle is forced into the shuttle box. The shuttle comes against thepivotally mounted plate 26, located betweenthe cheeks of the shuttle box1, at the end thereof. 27 are noses or projections on the plate 26 whlchengage under projections 28 provided on the forward partition 8, whichslides in guides 29 in the moving parts. The swinging over of the plate26 therefore raises the forward partition 8, so that the shuttle 25,pushed forward by slides 23 passes into the space in the shuttle box 1between the front partition 8 and the rear partition 5, in other wordsit comes into the forward end position in the shuttle box. The latterhas itself moved in the meantime so that it is close to the shuttlemagazine 24. Suitable recesses 30 are provided in the pivoted flap 26into which the'correspondingly formed slides23 can pass freely in casethere are no more shuttles in the shuttle magazine 24 to be pushed outby its movement.

That I claim as my invention and desire to secure by Letters Patent ofthe United States of America is I 1. In an automatic shuttle changingmech anism for looms the combination of a shuttle box; a springcontrolled rear wall pivoted thereto, providing for the ejection of anempty shut-tle; a vertically sliding front wall for said shuttle box; aswinging plate mounted forwardly of said sliding, front wall; a shuttlemagazine; means cooperating between said magazine and shuttle box forfeeding a full shuttle to said shuttle box, upon the operation of saidpivoted wall and the forward movement of said shuttle box; and meanscooperating between said swinging plate and said sliding front wall forraising the latter, as said full shuttle is advanced into engagementwith and past said swinging plate, to admit of the passage of said fullshuttle into operative position in said shuttle box, substantially asdescribed.

2. In an automatic shuttle changing mechanism for looms, the combinationof a shuttle box; a spring controlled rear wall pivoted thereto,providing for the ejection of an empty shuttle; a vertically slidingfront wall for said shuttle box, having a forwardly projecting member; aswinging plate mounted forwardly of said sliding wall, having arearwardly projecting member, engaging beneath the member on saidsliding wall; a shuttle magazine; and means cooperating between saidmagazine and shuttle box, for feeding a full shuttle to said shuttlebox, upon the operation of said pivoted wall and the forward movement ofsaid shuttle box, said swinging plate being disposed in the path oftravel of the advancing full shuttle, and the inward swing of saidswinging plate causing said sliding front wall to rise, to admit of thepassage of said full shuttle into opershuttle in said magazine and feedsame forward into said shuttle box; a lever engaging said slide foroperating the latter; a

longitudinally movable rod pivotally connected at one end to said lever,said rod having a projection thereon and being adapted to swing in avertical plane; a projection on said shuttle box adapted to engage theprojection on said rod when the latter is swung upwardly; means disposedbetween said pivoted wall and said rod for elevating the latter, whensaid pivoted wall is swung outwardly for ejecting an empty shuttle; andmeans for elevating said front wall upon the advancement of a fullshuttle, to admit of the passage of said full shuttle into operativeposition in said shuttle box, substantially as described.

4. In automatic shuttle changing mechanism for looms, the combination ofa shuttle box; a spring controlled rear wall pivoted thereto; avertically sliding front wall for said shuttle box; a swinging platepivotally mounted forwardly of said sliding wall; cooperatingprojections carried by said swinging plate and sliding wall to elevatethe lat ter upon the inward swing of said swinging plate; a shuttlemagazine; a slide member adapted to engage the lowermost shuttle in saidmagazine and feed same forward into said shuttle box, said sliding platebeing disposed in the path of travel of said advancing shuttle; a leverengaging said slide for advancing the latter; a longitudinally movablerod pivotally connected at one end to said lever, saidrod having aprojection thereon and being adapted vertical plane; a projection onsaid shuttle box adapted to engage the projection on said rod, when thelatter is swung upwardly and the shuttle box moves forwardly; and asystem of levers disposed between said pivoted rear wall and said rodfor elevating the latter when said pivoted wall is swung outwardly forejecting an empty shuttle, substantially as described.

In testimony whereof, I afiix my signature, in presence of twowitnesses.
